          Abstract

          Resumen En el Área Metropolitana de San Salvador el agua potable está en punto de estrés debido al cambio climático y el crecimiento urbano. Actualmente ocurren cambios en el ciclo hidrológico relacionados con la disminución de la infiltración y aumento de la escorrentía. El estudio de capas geológicas donde obras hidráulicas puedan ser factibles de construir o proyectar es el objetivo principal de esta investigación, considerando los beneficios, pero también teniendo en cuenta las posibles afectaciones, problemas en el sitio o infraestructura cercana. Muestras de suelo representativas fueron ensayadas en campo y laboratorio. Los resultados indican que los suelos tienen media-baja permeabilidad y que el agua infiltrada en las capas superficiales podría estar moviéndose horizontalmente debido a la litología en el área. Con la información geotécnica y geológica es posible obtener una zonificación preliminar y criterios para la infiltración artificial basada en las condiciones del suelo y la permeabilidad.

          Abstract In the Metropolitan Area of San Salvador resources as water for human consumption is at the point of stress with climate change and increased urban grown. Changes currently occur in the water cycle related to decreasing infiltration and increasing runoff. The study of geological layers where hydraulics works might be feasible to construct or project, is the main objective of this research taking into account all the possible affectations or issues in the site or even in near infrastructure like buildings. Soil representative samples were tested in the field and in laboratory. Results indicate that the soils are of medium-low permeability and that water infiltrated in surface layers might be moving horizontally due the lithology in the area. With geotechnical and geological information is possible to obtain a preliminary zoning and some criteria for the artificial infiltration based in the soil conditions and permeability.
